# SQL API Specifics

For SQL query limits and quotas per tier, see [Pricing](/pricing.md).

## Tables and schema discovery

While this documentation provides the tables' description it can always be generated by querying the table.

### List all available tables

```sql
SHOW tables from api
```

*Example Output:*

```
┌─name──────────────────────┐
│ market_future             │
│ market_option             │
│ market_spot               │
│ ohlcv                     │
│ trade                     │
└───────────────────────────┘

```

### Describe a table

```sql
DESCRIBE api.market_future
```

*Example Output:*

```
